Hi Gerard,
I donot use email now.. but it can be tried as attaching the expoort file to and from Headquarter and branch.
My practice now is that a Resided program writing in VFP in branch to generate the new and modified data in the system to a databse table file( This method is developed by me) at a interval time and then it also automatically dial the Headquarter's NT server by Remote Access Service throught modem (Branch donot require NT). After trammitted data to and from headquater and then disconnect modem line. There is a resided program in the headquarter to generate the export file and import the incoming files to the office system.

Regards,

Chau, Moon
